Definitions
- the present invention relates to a fluid circulation valve, in particular, the exhaust gas of a motor vehicle engine or a mixture of fresh air and exhaust gas.
- Said valve can thus be used to adjust an exhaust gas flow to be recirculated to the air intake line of the engine.
- it may be used in engine architectures, including diesel, turbo compressor, said valve being provided on the exhaust line of the engine downstream of the turbo compressor turbine to collect a portion of the gas.
- a valve comprising a body defining a main duct, for the flow of the exhaust gas, and an auxiliary duct, opening into said main duct and making it possible to take off the part of the exhaust gas intended to be directed towards the intake of the motor.
- Said valve comprises a movable flap between a closed position, preventing communication between the two ducts, and an open position, allowing the communication of said ducts. It also comprises a seal on which the flap is supported when in the closed position.
- a shutter actuation motor is provided and the valve body includes a housing for accommodating it.
- the exhaust gas flowing in the valve has a temperature of several hundred degrees and a difficulty to overcome in such a configuration is to protect the shutter actuation motor. For this, it is usually planned to make cooling ducts in the body of the valve. However, such a solution increases its size and causes an increase in the flow rate to be ensured in the cooling circuit used.
- the object of the present invention is to remedy these drawbacks and proposes for this purpose a fluid circulation valve, in particular an exhaust gas valve of a motor vehicle engine, comprising a body defining a main duct and an auxiliary flow duct. fluid, opening into said main duct, said valve further comprising a flap movable between a so-called closing position, preventing communication between the two ducts, and a so-called opening position, allowing the placing of said ducts in communication, and a joint sealing member on which the flap is supported when in the closed position, said body comprising a housing for an actuating motor of the flap.
- said body is configured to define a fluid blade between said seal and said housing. This improves the thermal insulation of the shutter actuation motor and the cooling needs of the valve are reduced. This makes it possible to optimize its dimensioning. In this way, it is also possible to use engines of less advanced technology because they must not withstand very high temperatures.
- the valve according to the invention comprises a body 30 defining a main duct 31 and an auxiliary conduit 32 for flowing the fluid, opening into said main duct 31.
- the main duct 31 has, for example, inlet orifices 34 and output communicating, in an application example, with the exhaust line of an engine.
- the auxiliary duct has an orifice 35 communicating, in the same application example, with an exhaust gas recirculation line.
- Said valve further comprises a flap 1 and a seal 2.
- Said flap 1 is provided movable between a closed position, preventing communication between the two ducts 31, 32, and an open position, allowing the communication of said ducts 31, 32, for example at a window 33 fluid passage.
- Said body 30 further comprises, for example, a housing 37 for an actuating motor of the flap.
- said valve may comprise a transmission system, not shown, between an output shaft of the motor and a shaft 21 of articulation of the flap.
- said body 30 is configured to define a fluid plate 38 between said gasket 2 and said housing 37. In this way, the thermal insulation of the motor 60 for actuating the flap is improved.
- Said body 30 may be made in two parts 30a, 30b, each part defining one of said ducts, and having an opening corresponding to define said window 33.
- Said seal 2 also plays a role of sealing between said two parts 30a, 30b vis-à-vis the outside of the valve.
- Said body 30 defines, for example, a bowl 61 between said seal 2 and said housing 37, said body comprising a wall 62 between said housing 37 and a bottom 65 of said bowl 61.
- the bottom 65 of said bowl 61 may be provided flat .
- Said bowl 61 and said housing 37 for the motor are defined, for example, by the part defining the auxiliary duct 32.
- the seal 2 has an opening 5 for the passage of the fluid from the conduit 31 to the other 32. Said opening 5 of the seal is provided, in particular, vis-à-vis the window 33 of the body 30.
- the flap 1 is provided for example, a first wing 3 and a second wing 4.
- Said first wing 3 called shutter wing, makes it possible to close the opening 5 of the seal, when the flap is in the closed position
- said second flange 4 called the other wing, makes it possible to close at least partially said first duct 31 when the flap is in the open position.
- the other wing 4 of the flap thus contributes to the thermal insulation of the engine
- Said seal 2 has, in particular, a blind zone 36, located vis-à-vis said other flange 4 when the flap 1 is in the closed position.
- the opening 5 of the seal is provided only at the level of the wing shutter 3, the shutter 1 being in the closed position.
- the fluid blade 38 is provided between said blind zone 36 of the seal and said housing 37.
- said first 3 and said second flange 4 extend from one side and the other side of the seal 2, transversely to the latter to let the fluid pass.
- the flap 1 is inclined with respect to the gasket 2 in its maximum open position, not shown.
- said shutter wing 3 and the other 4 of said wings are provided, for example, on either side of the seal 2, when the flap is in the closed position, and said flap 2 comprises an intermediate zone 6, connecting said first 3 and said second wing 4, passing through said opening of the seal, for example flush, at regions 7, 7 'of the contour of said opening 5 of the seal.
- Said gasket 2 comprises a flat zone 8 and, if we return to the figure 3 it can be seen that said flat area has a surface 9 against which said shutter wing 3 abuts by one of its faces, provided flat, said bearing face of the shutter wing, and / or an opposite surface 11 against which the other flange 4 of the flap bears, by one of its faces 12, provided flat, said bearing face of the other wing, when the flap is in the closed position.
- Said opening 5 for the passage of the fluid provided in the seal 2 is positioned at said flat area 8. The seal is thus formed by a face-to-face contact at the level of the said wing or wings.
- Said blind zone 36 of the seal 2 may also be located at said flat area 8 of said seal 2 in which the opening 5 of said seal is formed.
- the bottom 65 of said bowl 61 and said blind zone 36 are provided, for example, parallel to each other.
- Said bearing surface 10 of the shutter wing and said bearing surface 12 of the other wing of the shutter extend, for example, in two parallel planes spaced apart from each other, for example a dimension corresponding to the thickness of the seal in said planar zone 8. It is thus possible to provide plane-to-plane type contacts.
- the shutter wing 3 has a surface 13, opposite to its bearing surface 10, and the other wing 4 has a surface 14 opposite its bearing surface 12.
- These two opposite faces 13, 14 are, for example, example, planes and the intermediate zone 6 has an inclined portion 15 between the bearing face 10 of the sealing flange 3 and said opposite face 14 of the other flange 4. In this way the flow of the fluid is promoted. on the surface of the shutter.
- the valve may also include a hinge pin 16 of the flap 1, provided eccentric with respect to said flap 1 and located, for example, near the intermediate zone 6 of the flap.
- Said seal 2 has a boss 19 along a portion of the opening 5 of the seal, provided vis-à-vis the other flange 4 of the flap, when the latter is in the closed position. Said boss is configured to be compressed by said other wing 4 of the flap when the latter is in the closed position. This further improves the seal.
- the flap 1 has, for example, a housing 20 for the articulation shaft 21. This is, in particular, a hinge in rotation about the hinge axis 16, as illustrated in the figure 3 by the arrow marked 22. Said housing is, for example, in an extension 23 of the flap, located, in particular, in the intermediate zone 6. In such an embodiment, said extension 23 extends from the opposite face 13 to the bearing face 10 of the shutter wing and from the support face 12 of the other flange 4 of the flap.
- the housing 20 is here through and the shaft 21 opens on both sides of the housing 20.
- the shaft 21 is connected to the extension 23 in a manner known per se.
- the shutter wing 3, the other wing 4, the intermediate zone 6 and its extension 23 form, for example, a single piece, in particular from foundry.
- Said extension 23 of the flap accommodating its articulation shaft 21 is located so as to close the volume defined by the bowl 61 and the blind zone 36 of the seal 2, that is to say, so as to close said fluid blade 61.
- Said body 30 has for this, for example at the portion 30b defining the auxiliary conduit 32, housing 64 for the shaft 21 hinge flap.
- said shutter wing has a dimension y extending on either side beyond the dimension y 'along which the intermediate zone 6 extends, at least at a junction zone between said intermediate zone and said shutter wing.
- the bearing surface 10 of the sealing wing 3 may thus have a contact zone 17, in the form of an angular portion of a ring, with the seal 2, on a first part of the periphery of the opening 5 of the seal, one side of said seal, while the bearing surface 12 of the other flange 4 has, on the other side of the seal, a contact zone 18, on a complementary portion of the periphery of the opening 5 of the seal.
- the contact zone 17 provided by the shutter wing 3 also extends, for example, to the right of the intermediate zone 6, at the zones 7, 7 '. This reinforces the sealing and could have an intermediate zone 6 which does not flush the contour of the opening 5 of the seal.
- the opening 5 of the flap has a substantially rectangular contour, as well as the shutter 3. And the contact area 17 of said shutter wing 3 extends along three sides of said opening. As for the contact zone 18, it extends along the last side. Said intermediate zone 6 is provided vis-à-vis the contour of said opening 5 on a part of two of its opposite sides. Said other component 4 may also be rectangular.
- the seal 2 has, for example, a peripheral portion 39 and said planar zone 8 is set back from the peripheral portion. Such a seal is obtained, for example, by stamping.
- Said peripheral portion 39 may have extensions 40 forming a fastening flange on the body 30.

Le conduit principal 31 présente, par exemple, des orifices 34 d'entrée et de sortie communiquant, dans un exemple d'application, avec la ligne d'échappement d'un moteur. Le conduit auxiliaire présente un orifice 35 communiquant, dans le même exemple d'application, avec une ligne de recirculation de gaz d'échappement. - Ladite vanne comprend en outre un volet 1 et un joint d'étanchéité 2.
- Ledit volet 1 est prévu mobile entre une position de fermeture, empêchant la communication entre les deux conduits 31, 32, et une position d'ouverture, permettant la mise en communication desdits conduits 31, 32, par exemple au niveau d'une fenêtre 33 de passage du fluide.
- Ledit corps 30 comprend en outre, par exemple, un logement 37 pour un moteur d'actionnement du volet. Et ladite vanne pourra comprendre un système de transmission, non-représenté, entre un arbre de sortie du moteur et un arbre 21 d'articulation du volet.
- Comme visible aux
figures 2 et3 , selon l'invention, ledit corps 30 est configuré pour définir une lame de fluide 38 entre ledit joint 2 et ledit logement 37. On améliore de la sorte l'isolation thermique du moteur 60 d'actionnement du volet. - Ledit corps 30 pourra être réalisé en deux parties 30a, 30b, chaque partie définissant un desdits conduits, et présentant une ouverture venant en correspondance pour définir ladite fenêtre 33. On entend par là que lesdites deux parties du corps 30 sont distinctes, assujetties l'une à l'autre. Ledit joint d'étanchéité 2 joue alors aussi un rôle d'étanchéité entre lesdites deux parties 30a, 30b vis-à-vis de l'extérieur de la vanne.
- Ledit corps 30 définit, par exemple, une cuvette 61 entre ledit joint 2 et ledit logement 37, ledit corps comprenant une paroi 62 entre ledit logement 37 et un fond 65 de ladite cuvette 61. Le fond 65 de ladite cuvette 61 pourra être prévu plat.
- Ladite cuvette 61 et ledit logement 37 pour le moteur sont définis, par exemple, par la partie définissant le conduit auxiliaire 32.
- Le joint 2 présente une ouverture 5 pour le passage du fluide du conduit 31 à l'autre 32. Ladite ouverture 5 du joint est prévue, notamment, en vis-à-vis de la fenêtre 33 du corps 30. Le volet 1 est muni, par exemple, d'une première aile 3 et d'une deuxième aile 4.
- Ladite première aile 3, dite aile d'obturation, permet de fermer l'ouverture 5 du joint, lorsque le volet est en position de fermeture, et ladite seconde aile 4, dite autre aile, permet de fermer au moins partiellement ledit premier conduit 31, lorsque le volet est en position d'ouverture. L'autre aile 4 du volet participe ainsi à l'isolation thermique du moteur
- Ledit joint 2 présente, notamment, une zone borgne 36, située en vis-à-vis de ladite autre aile 4 lorsque le volet 1 est en position de fermeture. Autrement dit, l'ouverture 5 du joint n'est prévue qu'au niveau de l'aile d'obturation 3, le volet 1 étant en position de fermeture. Et la lame de fluide 38 est prévue entre ladite zone borgne 36 du joint et ledit logement 37.
- Dans une position d'ouverture du volet, ladite première 3 et ladite seconde aile 4 s'étendent d'un côté et de l'autre du joint d'étanchéité 2, de façon transversale à celui-ci pour laisser passer le fluide. Dans le mode de réalisation illustré, le volet 1 est incliné par rapport au joint 2 dans sa position d'ouverture maximale, non représentée.
- Comme illustré à la
figure 4 , ladite aile d'obturation 3 et l'autre 4 desdites ailes sont prévues, par exemple, de part et d'autre du joint 2, lorsque le volet est en position de fermeture, et ledit volet 2 comprend une zone intermédiaire 6, reliant ladite première 3 et ladite seconde 4 aile, traversant ladite ouverture du joint, par exemple de façon affleurante, au niveau de zones 7, 7' du contour de ladite ouverture 5 du joint. - On peut ainsi obtenir une étanchéité autour de l'ouverture 5 du joint tout en autorisant le débattement du volet entre sa position d'ouverture et sa position de fermeture sans avoir à laisser des jeux importants entre l'ouverture du joint et le contour du volet.
- Ledit joint 2 comprend une zone plane 8 et, si l'on revient à la
figure 3 , on constate que ladite zone plane présente une surface 9 contre laquelle ladite aile d'obturation 3 vient en appui par l'une 10 de ses faces, prévue plane, dit face d'appui de l'aile d'obturation, et/ou une surface opposée 11 contre laquelle l'autre aile 4 du volet vient en appui, par l'une 12 de ses faces, prévue plane, dite face d'appui de l'autre aile, lorsque le volet est en position de fermeture. Ladite ouverture 5 pour le passage du fluide prévue dans le joint 2 est positionnée au niveau de ladite zone plane 8. L'étanchéité est ainsi réalisée par un contact face contre face au niveau de la ou desdites ailes. - Ladite zone borgne 36 du joint 2 pourra aussi être localisée au niveau de ladite zone plane 8 dudit joint 2 dans laquelle est formée l'ouverture 5 dudit joint. Le fond 65 de ladite cuvette 61 et ladite zone borgne 36 sont prévus, par exemple, parallèles l'un à l'autre.
- Ladite surface d'appui 10 de l'aile d'obturation et ladite surface d'appui 12 de l'autre aile du volet s'étendent, par exemple, selon deux plans parallèles distants l'un de l'autre, par exemple d'une dimension correspondant à l'épaisseur du joint dans ladite zone plane 8. On peut ainsi assurer des contacts du type plan sur plan.
- L'aile d'obturation 3 présente une surface 13, opposée à sa surface d'appui 10, et l'autre aile 4 présente une surface 14 opposée à sa surface d'appui 12. Ces deux faces opposées 13, 14 sont, par exemple, planes et la zone intermédiaire 6 présente un pan incliné 15 entre la face d'appui 10 de l'aile d'obturation 3 et ladite face opposée 14 de l'autre aile 4. On favorise de la sorte l'écoulement du fluide à la surface du volet.
- La vanne pourra aussi comprendre un axe d'articulation 16 du volet 1, prévu excentré par rapport audit volet 1 et situé, par exemple, à proximité de la zone intermédiaire 6 du volet.
- Ledit joint 2 présente un bossage 19 le long d'une partie de l'ouverture 5 du joint, prévu en vis-à-vis de l'autre aile 4 du volet, quand celui-ci est en position de fermeture. Ledit bossage est configuré pour être comprimé par ladite autre aile 4 du volet quand celui-ci est en position de fermeture. Ceci améliore encore l'étanchéité.
- Le volet 1 présente, par exemple, un logement 20 pour l'arbre 21 d'articulation. Il s'agit, notamment, d'une articulation en rotation autour de l'axe d'articulation 16, comme cela est illustré dans à la
figure 3 par la flèche repérée 22. Ledit logement se trouve, par exemple, dans une extension 23 du volet, localisée, notamment, dans la zone intermédiaire 6. Dans un tel mode de réalisation, ladite extension 23 s'étend depuis la face opposée 13 à la face d'appui 10 de l'aile d'obturation et depuis la face d'appui 12 de l'autre aile 4 du volet. - Le logement 20 est ici traversant et l'arbre 21 débouche de part et d'autre du logement 20. L'arbre 21 est relié à l'extension 23 de façon connue en soi.
- L'aile d'obturation 3, l'autre aile 4, la zone intermédiaire 6 et son extension 23 forment, par exemple, une pièce unique, notamment issue de fonderie.
- Ladite extension 23 du volet accueillant son arbre d'articulation 21 est localisée de façon à fermer le volume défini par la cuvette 61 et la zone borgne 36 du joint 2, c'est-à-dire, de façon à fermer ladite lame de fluide 61. Ledit corps 30 présente pour cela, par exemple au niveau de la partie 30b définissant le conduit auxiliaire 32, des logements 64 pour l'arbre 21 d'articulation du volet.
- Tel que cela est illustré à la
figure 4 , selon la direction de l'axe d'articulation du volet, ladite aile d'obturation présente une dimension y s'étendant de part et d'autre au-delà de la dimension y' selon laquelle s'étend la zone intermédiaire 6, au moins au niveau d'une zone de jonction entre ladite zone intermédiaire et ladite aile d'obturation. La surface d'appui 10 de l'aile d'obturation 3 peut ainsi présenter une zone de contact 17, sous la forme d'une portion angulaire d'anneau, avec le joint 2, sur une première partie de la périphérie de l'ouverture 5 du joint, d'un côté dudit joint, tandis que la surface d'appui 12 de l'autre aile 4 présente, de l'autre côté du joint, une zone de contact 18, sur une partie complémentaire de la périphérie de l'ouverture 5 du joint. - La zone de contact 17 offerte par l'aile d'obturation 3 s'étend aussi, par exemple, au droit de la zone intermédiaire 6, au niveau des zones 7, 7'. On renforce ainsi l'étanchéité et on pourrait avoir une zone intermédiaire 6 qui n'affleure pas le contour de l'ouverture 5 du joint.
- L'ouverture 5 du volet présente un contour sensiblement rectangulaire, de même que le volet d'obturation 3. Et la zone de contact 17 de ladite aile d'obturation 3 s'étend le long de trois des côtés de ladite ouverture. Quant à la zone de contact 18, elle s'étend le long du dernier côté. Ladite zone intermédiaire 6 est prévue en vis-à-vis du contour de ladite ouverture 5 sur une partie de deux de ses côtés opposés. Ledit autre volet 4 pourra être lui aussi rectangulaire.
- Le joint 2 présente, par exemple, une partie périphérique 39 et ladite zone plane 8 est située en retrait de la partie périphérique. Un tel joint est obtenu, par exemple, par emboutissage. Ladite partie périphérique 39 pourra présenter des extensions 40 faisant bride d'accrochage sur le corps 30.
